J. P. LYNN PENCIL Filed Aug. l. 1927 Patented Aug. 5, 1930 UNITED ySTATES PATENT oFFlcE JOHN P. LYNN, OF CHICAGO, ILLINOIS, ASSIGNOR TODUR-O-LITE PENCIL COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OFILLINOIS PENCIL 'Application md August 1,

the body of the pencil.

' A suggestive embodiment of this invention is set forth in theaccompanying drawing wherein- Figurel 1 is a view in elevation of thepenj cil in its entirety;

Fig. 2 is an enlarged longitudinal section through the tip and proximateend of the pencil body;

Fig. 3 is a view in elevation of the tipl per se;

Fig. 4 is an enlarged transverse section taken on line 4-4 of Fig. 2;and 1 Fig. 5 is an enlarged fragmentary view,

partly in section, showing the tube enlargement which provides a bottomfor the magazine within the tip.

The present pencil comprises a 'body A having an axial chamber 6 whichopens out upon the lower end thereof. Associated with this end of thepencil is a tip member B which is frictionally and rotatably connectedwith the body.

The tip is preferably formed of metal with a headv having tapering walls7 preferably, straightened out as at 8, and then inturned at 9 toprovide a shoulder which may' abut the'pencil end. The tip walls whichare extended upwardly from this point are of reduced diameter in theform of a bod 10 which fits frictionally and rotatably wlthin thechamber 6 of the pencil. At its upper end the walls of the tip areinwardly inclined at 11 and terminate in a sleeve extension 12 which isinternally threaded for co-operation with a threaded plunger 14.

Mounted axially within the tip is a tube 15 Y which is confined in placeby the tapered. walls at its opposite ends. This tube forms a guide foran active lead C which is adapted 50 to be propelled by the plunger y111in response 1927. Serial No. 209,656'.

to rotation thereof relative to the tip. The general constructiondescribed up to this point has heretofore been known, and no claimthereto is here advanced.

The present invention is concernedwith the provision within. the Atip ofa magazine for accommodating reserve leads. As shown, several of suchleads D are arranged annularly within the space surrounding the tube 15.The lower ends of these leads may be rested against a shoulder 16 whichis formed conveniently by expanding at one point the material formingthe tube. This shoulder which extends substantially to the proximateportions of the tip walls 7 forms a bottom for the magazine in which theleads are received. `At its upper end' this magazine is closed by thetapering walls 11, the leads being conflned in place in this region ofthe tip between its body portion 10 and tube 15. Access to the magazineis aorded by a slot 17 which extends vertically on one side of the tipbody 10,V the slot also continuing laterally as at 18 in the shoulderportion'9.

When the tip is assembled with the pencil,

the slot 17 is closed so as to prevent removal of any reserve lead. Byseparating the tip from the pencil, however, the'slot is uncovered sothat the upper end of one of the leads may tilt outwardly through theslot so as to be presented conveniently for grasping. It

may then be pulled out by hand, or, 'if de# sired, the tip may beinverted to induce removal of the lead by gravity.

In the construction of a tip which ts frictionallyand rotatively withina chamber in the lower body end, it is desirable to provide, ifpossible, some sort of spring action which will assure of a properconnection at all times. This may be best accomplished by slightlybowing from end to end the walls of the tip body 10, and providingtherein one or more slits to leave intervening spring sections whichwill bear frictionally against the walls of the pencil body. In thepresent invention the slot 17 which is the door to the magazine serves'admirably to permit of such spring action, so that the tip is assuredat all times of a desirable. connection with the body of the pencil.

I claim: l. A pencil having a body with an axial chamber open at itslower end, and a tip applied to said end of the body, the tip beingprovided with a body portion which is extended into the chamber of thepencil body for frictional connection therewith, the tip being hollowand having in its body portion a slot extending longitudinally of thepencil through which reserve leads maybe passed into or out of the tip,the slot being closed when the tip is assembled with the pencil body,substantially as described.

2. A pencil in which is combined a body having an axial chamber open atits lower end, a tip having a portion receivable within the chamber tofrictionally engage the walls surrounding the same, there being a slotformed longitudinally through the walls of said portion adapted to bewholly closed by the body walls when the tip is assembled with the body,and a tube arranged axially within the tip in spaced relation to thewalls thereof providing an annular chamber wherein reserve leads may beaccommodated, the leads being removable through theslot only when thetip is separated from the body of the pencil, substantially asdescribed.

v3. A pencil in which is combined a body having a chamber open at thelower end thereof, and a hollow tip formed with walls which extend inpart within the chamber. for frictional connection therewith, the tipbeing provided with a central tube in spaced relation to its wallswhereby there is formed an annular chamber within the tip, a portion ofthe tube being laterally expanded at one point toform a bottom for themagazine with-Y in the tip, there being provided in the walls of the tipwhich are engaged "by the pencil body a slot through-which a reservelead may pass, the slot being wholly covered when the tip is assembledwith the pencil, substantially as described.

4. A pencil -in which is combined a body having a chamber open at itslower end, a

hollow tip receivable in part within the cham-,

ber for connection with the'pencilbody, a

tube arranged axially within the tip in spaced relation to thesurrounding walls thereof, the space between the tube and tip beingclosed at both ends whereby to provide a magazine for reserve leads,there being aI slot formed longitudinally through the walls 'of the tipbetween the ends thereof a'ording access to the magazine interiorly ofthe latter, the slot being so located as to be covered by the walls ofthe pencilY body'when the tip is assembled therewith, substantially asdescribed.

'5. In a pencil comprising abarrel, a removable tip therefor including atapered end and a reduced sleeve portion extending into the barrel intelescopic engagement therewith, and lead-propelling means including.

a plunger disposed axially in said sleeve and by the tipv and removablefrom the barrel' therewith.
